PROCESS OF FORMING WALLS.

Specification of Letters Patent.

Patented Feb. 6, 19117.

Application filed June 21, 1915. Serial No. 35,195.

To all whom it may concern:

Be it known that we, EDWARD CONNELLEY and CHARLES C. CREW, citizens ofthe United States, residing at Houston, in the county of Harris andState of Texas, have invented certain new and useful Improvements inProcesses of Forming Walls, of' which the following is a specification.

This invention relates to new and useful improvements in a process offorming walls,

or other. plastic material.

The object of the invention is to provide a process whereby a wall maybe constructed from concrete or other similar material without the useof molds. As is well known concrete as now employedin the erection ofbuildings is applied in the formation of the structure only by theassistance of molds,

which must first be erected and the material in its plastic state thenpoured thereinand allowed to set or harden and the molds are thenremoved. .This process adds to the labor and expense of erecting thestructure and it is the object of this invention to obvlate thenecessity of using molds and to provide a process whereby the walls maybe erected without employing molds.

With the above and other objects in View, the invention has particularrelation to a novel process, which will be more specifically set forthin this specification, said process being also illustrated by means ofthe accompanylng drawings, wherein:

Figure 1, is a fragmentary side elevation of a wall.

Fig. 2,is a fragmentary transverse sectional view of a partiallycompleted wall.

Figs. 3 and 4, show fragmentary transyerse sectional views of a wall,constructed in accordance with said process and,

Flgs. 5 and 6, show fragmentary transverse sectional views of modifiedforms of wall.

In carrying out the process herein described, reticulated partitions, as1, 1, are placed in position and secured in fixed relat on to each otherby means of any suitable kind of supporting spacers. In the drawingsordmary studding 2, is shown, to the opposite sides of which thereticulated walls, 1, 1, are secured and by means of which they Thewalls 1, 1, are formed of wire mesh or other similar open work and aresecured against spreadmg between the studs 2, by means of suitablecrossrods as a, and the space between them is then filled with gravel orsome other suitable coarse aggregate. The spaces between the particlesof the aggregate are then filled from either or both sides with mortar,grout or some other similar cementing material. This material is firstreduced to a semi-liquid or fluid state and is forced through thereticulated walls and into the spaces between the particles of aggregateby hand, or a pneumatic jet, cement gun or any other suitable means. Theprocess of applying the grout may be continued so as to form aplaster'or stucco finish for the wall of the desired thickness at asingle operation for each face. Where a solid wall is undesirable butair spaces within the same are required, the penetration will not beallowed to reach the center, the same being regulated by the directionand force of the application or by increasing the thickness of the wall.In this manner air spaces may be left at the center of the wall tointerrupt the conduction of heat and moisture. In case refrigerator orcold-storage walls or heat retainirig walls are desired a cork board orother non-conducting material of the required thickness may beintroduced to form a core in the wall.

In case a very thick wall is required, it may be found desirable tosecure to the frame work within the reticulated walls 1, 1, similarreticulated partitions 5, 5, which are spaced a short distance apart andarranged parallel with the walls, 1, 1. The spaces between the wall 1,and the corresponding partition 5, on each side are then filled withgravel and the fluid concrete composition, or grout, applied to eachside of the wall, as hereinbefore explained and the space between thepartitions, 5, 5, also filled with said composition. The compositionwill find its way through said walls, 1, 1, and partitions 5, 5, andwill fill the spaces between the gravel in the manner hereinbeforeexplained, so that when the composition has hardened, a wall of solidconcrete throughout will result. 1

It is obvious that in the construction of walls of unusual thickness, anumber of spaces, such as is provided between the partitions 5, 5, maybe arranged for, for the introduction of the cement composition to theinterior portion of the wall.-

Another form of wall embodying the process herein set forth consists ofa solid wall formed, for example of brick and a loo -- walls on eachside of the structure so as to fill ,the spaces between the particles ofaggregate only part of the way to the center of the structure and leavethe center of the structure free from the plastic material to permit theair to circulate between the particles of the aggregate. I 2. Theprocess of forming a structure consisting of securing wire mesh walls inspaced relation to each other, then filling the space between said wallswith coarse aggregate, then forcing plastic material by means of aspraying device against the outer side of each of said walls andcontinuing said operation until said material-penetrates said wire meshand fills the spaces between the particles of aggregate only part of theway to the center-of the structure on each side, leaving the center ofthe structure free from the plastic material to form an air space in thecenter of the structure.

In testimony whereof wehave signed our names to this specification inthe presence of two subscribing witnesses.
